Allow the xqueue session engine to be configurable.

We removed use of these templates after platform removed yaml

While we'll eventually switch back, having unused templates around is
confusing.

Other code removed in 8f16fd28

This defaults to http://localhost:18040 but needs internal hostname

Update sqoop 1.4.6 package download url

XQueue wasn't using this argument and it was removed

* Updating analytics jenkins role to work again, and to be more consistent with current codebase patterns

* Updating analytics jenkins role to work again, and to be more consistent with current codebase patterns. Moved jenkins.j2 to the directory with other j2 templates

It now throws an error from Django if you pass in the unused parameter.

Upgrade mongo agent (OPS-2290)

Add an xqueue_env file

Consolidate edxapp update assets scripts.

The asset compilation scripts edxapp-update-assets-lms and
edxapp-update-assets-cms duplicate a lot of work between them. Running
webpack twice also seems to cause an intermittent error where the
second build results in a different bundle hash than the first.

It is possible to run "paver update_assets" without specifying "lms" or
"cms", in which case it just compiles it all at the same time. This
removes the duplicate invocations of webpack and should speed the build
overall.

Much of our deployment infrastructure relies on having the settings and
path controlled from the environment file.  We don't have a good
way yet to define the CONFIG file since there is an auth and an env.
There's a later ticket for that.

Clarify ambiguous task step name

Have update_users only happen when services are running

Right now, it would run unless you are skip-tags'ing it (which is sort
of what we do in docker builds) or if the image has access to a database
(which is what happens during production builds).  It should instead be
explicitly requested.  I would remove it entirely, but we really want it
to run during sandbox builds, which use the ansible role.
